heat from the engine exhaust to keep the occupants comfortable.

Another object is to provide an improved form of radiator employing aliquid heating medium which in turn is adapted to receive heat from themotor or engine.

Another object is to provide means for obtaining a circulation of theliquid heating medium.

It further consists in certain details of form combination andarrangement all of which will be more fully described in connection withthe accompanying drawings in which:

Figure 1 is a diagram in top plan view'of my improved apparatus. Fig. 2is a side elevation of the same. Fig. 3 is a central verticalsectionthrou'gh one of the radiators onlinec'vofFigL' In theaccompanying drawings A represents the propelling-motor of anautomobile, whichmay be a steam engine but is preferably an explosionengine. B represents the exhaust pipe leading-therefrom,

C C represent radiatorsor heaterspreferably let into the floor b of thecar in front of the respective car seats and with their upper facesflush with the car floor. Said radiators comprise hollow metal shellswhich may be cast if desired, but are preferably formed from stamped ordrawn sheet metal sections which are united by welded joints at c 0. Apartition D divides each of said radiators into two compartments d d.The :ompartments d receive the heated exhaust which is diverted to thedesired extent fromthe exhaust pipe B by means of a controlling valve dfrom'which the diverted exhaust p'asses'by pipe E to compartment d ofradiator C thence by'pipe e to compartment 65 of radiator O and thenceby pipe 0 is returned to theexhaust pi e B and escapes to the airthrough the mu er B. The com- H represents a tank ably water with theaddition of a substance to-sufliciently lower its freezing point toavoid freezing under normal conditions. The liquid being in contact withthe part of the radiatorin contact with the floor and articles ofclothing of the occupants prevents temperatures high enough to dodamage,

and provides a uniform heat of the quality required.

or reservoir which is preferably located beneath one of the car seatsand at, a level slightly above the radiators. Said tank is connectedby apipe 71. with the compartments 0? of the respective radiators to providean escape from said compartments to said tank of any vapors generatedtherein.' A pipe 71/ is also preferably provided at the opposite end oftank H and connected thereto at a lower level than pipe h, said pipe it.bein also connected to the compartments cl, and therebyproviding for acirculation of the liquid from tank H by pipe 71 through the respectivecompartments d and back to tank H by pipe h. The tank H is preferablyprovided with a blow oft valve K to prevent excessive pressures.

The mechanism herein illustrated and described is capable ofconsiderable modification without departing from the principle of myinvention.

Having described my invention what I claim is: I

1. In a mechanism of the character described, a motor, an exhaust pipeleading from said motor,,a radiator having a substantially horizontalupper face to occupy a position flush with the floor of a car andcomprising a shell divided by a cap shaped partitioninto an upperchamber and a-lowe-r chamber with the upper chamber embracing the topand sides of the lower chamber, connections at the side of said radiatorthrough whichto circulate a liquid to and from said upper chamber, andconnections near oppo site sides at the bottom of said lower chamber tocirculate the motor exhaust from said exhaust pipe through said lowerchamber.

2. In a mechanism of the character described, a motor, an exhaust pipeleading Patented May 5, 1914.. I

' partments d of the respective radiators are I filled with a liquidheating medium, prefer-' and sides by said partition from said uppercompartment, said upper compartment being provided with pipe connectionsat its sides to provide for the circulation of a liquid heating mediumtherethrough, and said lower compartment being connected at its underside at one end by a valve controlled pipe with said motor exhaust pipeand at the opposite end of its lower side with an exit port to providefor circulating a regulated portion of the motor exhaust through saidlower chamber,

3. In a mechanism of the character described, a motor, an exhaust pipeleading from said motor, a radiator comprising a shell divided by asubstantially horizontal partition into an upper compartment adapted tocontain a liquid heating medium and a lower compartment provided with avalve controlled inlet pipe leading from said exhaust pipe, and an exitport to provide for a circulation of the motor exhaust through said lastnamed compartment, a tank located at a higher level than said radiator,a pipe connecting the upper portion of said tank with said first namedcompartment of the radiator, and a pipe connecting the lower portion ofsaid tank'with said first named compartment of the radiator.

In testimony whereof I have afiixed my signature in presence of twoWitnesses.
